The utility model discloses a control switch in an embodiment, which can effectively improve the condition that a user is too dazzling due to a key indicator lamp in the use process at night so as to improve the use comfort of the switch.

As shown in fig. 1, the control switch of the present utility model includes: a base 10, at least one key 20, a mounting frame 30, and at least one light module 40. In connection with fig. 2 and 3, in particular, the base 10 is connected with a switch function module 101. The key 20 is used for realizing pressing actions in two directions so as to control the breaking or the switching-on of the switch circuit. The mounting frame 30 is connected between the base 10 and the key 20, and at least one light guide channel 301 is disposed on the mounting frame 30, so as to facilitate guiding out the light outputted by the light source from the inside of the cavity of the bottom shell along the key direction. The at least one light emitting module 40 is embedded in the cavity of the base 10, and each light emitting module includes a light emitting element 41 and a light guiding element 42. The light emitting element 41 is connected to the control switch function module 101, and one end of the light guiding element 42 is adjacent to the light emitting element 41, and the other end thereof is connected to the light guiding channel 301 of the mounting frame 30.

It will be appreciated that when the key 20 is pressed to a switch-on position, the switch circuit of the control switch is in an on state, and the light emitting module 40 is in an off state; when the key 20 is pressed to a switch-off position, the switch circuit of the control switch is in a breaking state, and the light emitting module 40 is in an operating state. According to the structure of the utility model, the light finally led out by the light emitting module 40 does not directly penetrate the exposed surface of the key 20, but is led out through the light guide channel 301 on the mounting frame 30 by multiple light refraction, and finally irradiates on the wall surface, so that the light becomes softer, and the sense of the user using the device in the night mode is effectively improved.

According to the control switch of one embodiment of the present utility model, the cavity of the base 10 is provided with at least one first mounting groove for accommodating at least one light emitting element 41 and at least one second mounting groove for accommodating at least one light guiding element 42, so as to ensure compactness of the internal structure of the switch.

Referring to fig. 3 and 4, according to an alternative embodiment of the present utility model, the light guiding element 42 of the control switch includes: a first bend 421 and a second bend 422. Specifically, the first bending portion 421 is adjacent to the light emitting element 41. The second bending portion 422 extends along a direction close to the outer edge of the mounting frame 30, so as to avoid direct access to the outer surface of the key 20, thereby skillfully solving the problem that light rays directly enter eyes through the key surface.

As an alternative embodiment, as shown in fig. 4 and 5, the light emitting element 41 of the present utility model is a columnar body that maintains a coaxial positional relationship with at least one end of the first bending portion 421. For example, the column may be an LED bulb. Because the luminous head of the LED bulb and the end part of the first bending part 421 are kept coaxial, the accurate transmission of the light source can be effectively realized, and the high-efficiency conduction of light rays in the inner cavity of the bottom shell is realized.

As shown in fig. 2, in the control switch according to still another embodiment of the present utility model, preferably, the light guiding element 21 further includes a third bending portion 423. The third bending portion 423 is connected between the first bending portion 421 and the second bending portion 422, and a fastening portion 423a is provided on the third bending portion 423, so as to be connected to the pressing plate of the key 20, thereby achieving a relatively stable positioning effect.

In view of the optimized design of the light source scattering effect of the control switch, as an alternative embodiment, the light emitting element 41 and the light guiding element 42 are disposed on the same side of the base 10 and located near the end of the key 20, which also ensures the compactness of the overall structure of the light emitting module.

Referring to fig. 4 and 5, as two different embodiments of the control switch of the present utility model, the light guide channel 301 is a through slot disposed on one side of the mounting frame 30, and the through slot may be a strip channel, a column channel, or other forms. It should be understood that the shape and structure of the through groove are not unique, so long as the through groove is matched with the shape and structure of the second bending portion 422, that is, those skilled in the art may also take other shapes or structures matched with each other to specifically implement the corresponding function, and the utility model is not limited thereto.

Optionally, in the solution of the control switch of the present utility model, in order to further increase the light refraction effect and weaken the intensity of the light, according to a specific embodiment of the control switch of the present utility model, a first refractive slope s1 for implementing a first refractive path is further disposed between the first bending portion 421 and the third bending portion 422. Further, a second refractive slope s2 for realizing a second refractive path may be further provided between the second bending portion 422 and the third bending portion 423. Due to the existence of the first refraction inclined surface s1 and the second refraction inclined surface s2, light rays can be transmitted according to needs through different refraction paths, and better visual experience is brought to users.

It is worth pointing out that the design of the utility model effectively avoids the light holes being formed on the surface of the key, thereby avoiding unnecessary irritation to eyes of a user caused by direct emission of glaring light on the surface of the switch key in a night mode. Correspondingly, as shown in fig. 4 and fig. 5, the control switch of the present utility model has a through groove formed on the mounting frame 30, so that the end 422a of the second bending portion 422 extends outwards and fills a part of the exposed surface of the mounting frame 30, the light emitted by the light source is refracted through the plurality of bending portions, and finally the light that is transmitted out of the mounting frame is not dazzling any more, but the light emitting surface is transferred to the position below the switch, and further irradiates the wall surface to be softer, so that the user can easily find the position of the switch at night, and can help to create a higher-level illumination environment without a main lamp, and greatly improve the comfort of the use of the user.

It will be appreciated by those skilled in the art that the number of keys 20 and switch function modules 101 in the control switch of the present utility model is not limited, and for example, the control switch may be a single key control switch, a double key control switch, a triple key control switch, or a four key control switch as shown in the drawings, and modifications and variations of these designs are within the scope of the present utility model.

In summary, the scheme of the utility model does not need to provide the light holes on the surface of the key, so that too abrupt direct light is prevented from entering eyes of a user, but the light guide channels such as through grooves are arranged on the mounting frame, so that the light is optimized in the transmission path, and finally scattered out through the wall surface, the problems existing in the existing products are effectively solved, the light felt by the user is softer, a more comfortable home light environment atmosphere is created, the use sense of the user is improved, and the method has wide applicability.
